Electric field of moving charge

When a charge start motion it produce magnetic field.Is this cause any change in electric filed of this charge?and when there is no acceleration in this charge it will have magnetic field?also is this is relative velocity?

A charge with uniform velocity will have a different electric, and magnetic field than a stationary charge. The magnetic field is easy to understand if you view the moving charge as a current. The electric field change can be understood by lorentz contraction of the electric field lines. The lines parallel to motion are unchanged, but the lines perpendicular to motion get squished together.
